Charnas and Henick declined to comment on the sale, and representatives for the Naftali Group and Buchbinder & Warren did not respond to requests for comment.

Naftali purchased 1041 Madison Avenue in September for $21.1 million, and the company purchased 1045 Madison Avenue in October for $22.8 million, according to property records. The developer’s last remaining parcel is in the Davide Cenci building at 1043 Madison Avenue, where a deal is expected to close in about two weeks.

The Upper East Side assemblage marks Naftali’s reentry into purchasing New York real estate roughly two years after Miki Naftali said his company would focus on its active projects instead of seeking out new ones due to the prohibitively expensive price of land.
